Speer Bullets developed Grand Slam to provide better integrity and retained weight. It has grown to be one of the most respected and successful big game bullets in the world. Grand Slam has superior performance which translates to exceptional accuracy and real knockdown power. A tapered, precision-drawn jacket makes for reliable expansion. And internal flutes at the jacket opening mean symmetrical and consistent expansion. The long nose profile produces flatter shooting. When the game you seek is at the top end of your rifle's capability, you need a tough bullet. You need Grand Slam.
